The invention relates to lamps and more particularly to lamps designedfor use within the interiors of closed motor vehicle bodies. One of theobjects of the invention is to provide an improved lamp designed toilluminate by indirect lighting. Another object is to provide a lamphaving a body and a shield detachably secured to the body by means ofwhich indirect lighting is provided for and the light bulb may bereadily removed and replaced. A further object is to provide a body anda shield which may be formed of sheet metal and which when securedtogether will not rattle. With these as well as other objects in view,the invention resides in the novel features of construc tion andcombinations and arrangements of parts as more fully hereinafter setforth.

In the drawing Figure 1 is a front elevation of a lamp embodying myinvention;

Figure 2 is a side elevation thereof;

Figure 3 is a front elevation of the lamp body;

Figure 4 is a cross section on the line 4-4 of Figure 3 and showing theshield secured to the body.

The lamp illustrated is a corner lamp designed for use within theinteriors of closed motor vehicle bodies and comprises the lamp body 1and the shield 2 which is detachably secured to the body. This body ishollow or dish-shaped and its inner surface preferably forms thereflector for the light rays. The sides of the body have the openings 3through which suitable securing means such as screws may be inserted tohold the body securely to the supporting member. The body is formed withthe rim 4 surrounding the elliptical light opening 5 and also is formedwith an opening in its upper end for insertion of the light bulb socket.

The shield covers the portion of the light opening 5 opposite the lightbulb and its socket and is located within the inner edge of the rim 4:.To position the shield relative to the body so that this shield forms ineffect a continuation of the rim, the sides of the body opposite thelight bulb and its socket are depressed inwardly to form the periph-Serial No. 164,942.

orally extending shoulder 6 which is spaced from the rim. The shield isprovided with the peripherally extending bead 7 engageable with thisshoulder when the shield is in place. For detachably securing the shieldto the body the inwardly depressed sides of the body below the shoulder6 are punched inwardly to form the oppositely located projections 7. Theshield is formed with the side flanges 8 which are adapted to extendinto the body below the shoulder and are provided with the recesses 9for engaging the projections 7. These side flanges are resilient so thatthe shield can be detached or replaced when desired, as for example whenremoving a light bulb and replacing another.

Both the body and shield are so constructed that they may be formed ofsheet metal, thereby providing for the economical manufacture of a lightweight lamp which illuminates by indirect lighting and in which thelight bulb and its socket are ordinarily concealed.

What I claim as my invention is:

1. A lamp for vehicle bodies having in combination a hollow body havinga light opening, and a rim surrounding the light opening, and a shielddetachably secured to said body and covering a portion of the lightopening, said body having an inwardly depressed portion spaced from saidrim and forming a shoulder for positioning the said shield relative tosaid body.

2. A. lamp for vehicle bodies having in combination a body having alight opening and a shield covering a portion of the light opening andprovided with resilient securing portions extending within said body fordetachably securing said shield to said body.

3. A lamp for vehicle bodies having in combination a sheet metal bodyhaving a light opening and a rim surrounding the light opening, aportion of said body being in- Wardly depressed to form a peripherallyextending shoulder spaced from said rim, and a sheet metal shieldcovering a portion of the light opening and located within the inneredge of said rim, said shield having a bead engageable with the shoulderof said body and having resilient side flanges extending Within saidbody for detachably securing said shield to said body.

5 In testimony whereof I afix my signature.
